Confirmed.
Here a more tiny code:
clr =
#(define-scheme-function (val m) (number-list? ly:music?)
#{ \tweak color #val $m #})
{ b1 \clr 1,0,0 b }
\lyrics { foo \clr 1,0,0 bar }
Obviously a number-list in ly-syntax is not understood in lyrics.
The example could be fixed by using scheme-syntax instead: 1,0,0 -> #'(1 0 0)
David, a parser problem?
Cheers,
Harm
